 4. **Drop overlay**: dragenter with Files shows the copy exactly; dragleave hides; drop starts uploads; a drag without Files shows nothing; mobile pinned button hidden while shown.
 5. **Queue**: 6 valid files give at most 2 XHRs open at once; order kept; header "Uploading 6 images" and "N of 6 done" counts settled rows; "Uploading 1 image" singular; progress 1.1 of 2.6 MB reads "Uploading 1.1 of 2.6 MB" with a 42 % bar; 201 gives "Added to your library"; a silent list reload follows; files added while open are appended.

 9. **Summary**: Examples-driven summary lines; "Upload finished" / "{n} images" and "Dismiss"; "Nothing was uploaded" with "3 files were rejected" and with "2 files need attention", no summary; live-region text; Dismiss removes every row.
